Pixie has been making the most of her time in Los Angeles, celebrating Halloween at Chateau Marmont in West Hollywood last weekend and attending the BAFTA Britannia Awards.

Before jetting to America, the star enjoyed a well-earned holiday in Chania, Crete, with model boyfriend of five years, Oliver Cheshire, 28, after starring in the West End production of Breakfast At Tiffany's.

Pixie appeared in the production as Holly Golightly at the Royal Haymarket Theatre from June to September, but the role has now been taken over by Georgia May Foote.

The musical pair crossed paths as Pixie prepared to hand over the baton, and it seems that two actresses have really hit it off.

'I gave her my number,' the Mamma Do beauty told MailOnline when quizzed on how well they got on.

'We crossed over on the last couple of days because she was coming in to rehearse. It was great to finally meet her. She was excited and really lovely.'

Pixie and Oliver have been dating since late 2010, but the pair have no plans to take their relationship to the next level yet.

Speaking to Notion magazine last year, she said: 'Honestly, people are obsessed with it! I don't know, I always get asked "when are you getting married?"

'As soon as I started going out with Oliver I was asked it, and I still get asked in it every interview.

'I don't know why that is, maybe it's just something that people want to hear about, I don't know. I think male celebrities probably don't get asked it as much.'
